Cricket South Africa (CSA) CEO Gerlad Majola regretted the decision of the former vice captain to quit international cricket and said, ''It is with regret that we learnt of Nickys decision because his inclusion in the Castle Test Squad to play against India shows that the selectors still have faith in him at this level.
''However, we have to respect his decision to concentrate on playing for the Gestetner Diamond Eagles. Nicky has been a committed cricketer wherever he has played the game and has been a role model for all young players. We are grateful that he will still be part of the game in South Africa,'' he explained.
Boje, earlier, faxed a letter to the CSA chief executive conveying his decision to retire from international cricket immediately.
''I have had 11 years of international cricket and will always cherish wonderful memories of playing for South Africa. I now feel that the time has come for me to devote the remainder of my playing years to the Gestetner Diamond Eagles cricket.
''I wish my former team mates in the Proteas side the very best for the future and I am confident that the team has a bright future,'' Boje wrote.
A left-handed orthodox spinner and lower order batsman, Boje made his ODI debut for South Africa against Zimbabwe in 1995 and played his first Test in 2000 against India in Mumbai.
The 33-year-old spinner played 43 Tests in which he took 100 wickets at an average of 42.65 and also scored 1312 runs at an average of 25.23.
He was selected as a member of a 15-man squad to play against India in the three-match Castle Test Series beginning at Liberty Life Wanderers here on Friday.
